These excellent connections are the product of my superb brain and I reserve the right to use them in my Ph.D.
Do you know what else was going on in 1947?
It gets more interesting - or contrived - when you click on these funky links regarding Admiral Byrd and Operation High Jump.
Apparently Admiral Byrd while flying over the Pole got caught in a traction beam and entered the planet through a hole, meeting inner worlders who had superior technology and held his plane in remote control so he could land and discuss things - confidentially.
However I wasn't there in 1947, and probably neither were you, so caution is required when investigating secret sub-histories as the past may be re-written for contemporary political purposes, and conspiracy theories get derided, but you know that. Tab 1/11/04
